Seb kub-melt adhesive zaj duab xis thiab tus kheej-nplaum yog tib cov khoom, lo lus nug no zoo li muaj cov neeg coob coob. Ntawm no kuv tuaj yeem qhia koj kom meej meej uas kub yaj adhesive zaj duab xis thiab tus kheej-nplaum tsis yog cov khoom qub. Peb tuaj yeem nkag siab luv luv qhov sib txawv ntawm ob los ntawm peb yam no:
1. Qhov sib txawv hauv tsev pheeb suab zog: kub melt adhesive zaj duab xis yog ib qho kev ua kom sov. Nws yog lub xeev ruaj khov nrog kev ua haujlwm ruaj khov ntawm chav sov thiab tsis muaj viscosity.
Nws yuav nplaum tsuas yog thaum nws tau melted, thiab nws yuav solorify tom qab txias txias, tsis muaj tus nplaum, tsis muaj qab zib, me ntsis xws li yas. Muaj ntau hom halt adhesive cov yeeb yaj kiab, thiab sib txawv hom kub yaj cov lus qhia zoo sib txawv, uas tau npog qhov nruab nrab, thiab kub thiab txias. Tus kheej cov nplaum yog qhov ua tau tus kheej. Lawv yog cov nplaum ntawm chav sov. Lawv kuj muaj lub ntsiab lus melting, tab sis feem ntau tau melting point yog tsawg heev, txog 40 degrees. Qhov qis dua lub zog melting, qhov qis dua qhov ua kom muaj zog tom qab txias, uas tseem yog ib qho zoo tshaj plaws vim li cas tus kheej nplaum yog yooj yim rau lub kua muag tom qab tau dhau los.
2 Qhov sib txawv ntawm kev tiv thaiv ib puag ncig: nws yuav tsum tau hais tias ib puag ncig kev tiv thaiv ntawm ntau kev lag luam, thiab nws kuj tseem yog cov xeeb ceem ntawm kev tiv thaiv ib puag ncig uas tau siv dav. Kev tsim khoom thiab kev ua tus nqi ntawm kev tsim qauv tus kheej yog qhov tsis muaj kev tiv thaiv tsawg, tab sis nws txoj kev tiv thaiv ib puag ncig tsis sib piv rau qhov uas kub yaj adhesive zaj duab xis.
3. Qhov sib txawv hauv txoj kev siv: Kev siv Kub Melt Adhesive zaj duab xis tsuas yog cia siab rau cov khoom sib txuas rau cov ntaub ntawv. Tus kheej-nplaum muaj qhov tsawg melting point thiab yog kua, uas yog qhov nyuaj ua rau lwm yam duab. Cov txheej txheem ntawm "kev txhuam hniav" feem ntau yog siv thaum ua cov kua nplaum. Qhov tsis zoo ntawm hom no yog tias cov kua nplaum yog thaiv cov hws ntawm cov ntaub, ua rau airtightness.
